(Background of the Invention)
The present invention relates generally to medical and / or robotic devices, systems and methods. In an exemplary embodiment, the present invention provides one or more robot manipulator assemblies for communicating the state of a manipulator assembly or other component of a robot system for identification of one or more specific manipulators or the like. Provide indicators related to The indicator may provide an additional user interface between the robotic system and, for example, a surgical assistant, system operator, or the like.

  Minimally invasive medical techniques are intended to reduce the amount of extraneous tissue that is damaged during diagnostic or surgical procedures, thereby reducing patient recovery time, pain and adverse side effects. One effect of minimally invasive surgery can, for example, reduce hospital recovery time after surgery. The average hospital stay for standard surgery is typically significantly longer than the average hospital stay for similar minimally invasive surgery, so the increase in the use of minimally invasive techniques saves millions of dollars in hospital costs each year Can do. Many surgeries can save millions of dollars in hospital costs each year. Many of the operations performed in the United States each year may be performed in a minimally invasive manner, but due to the limitations in minimally invasive surgical instruments and the additional surgical training involved to learn them, Only the part uses these advantageous techniques.

  Minimally invasive robotic or telesurgical systems have been developed to increase surgeon dexterity and avoid some of the limitations of traditional minimally invasive techniques. In telesurgery, the surgeon uses some form of remote control, such as a servomechanism or the like, rather than directly grasping and moving the instrument to manipulate the movement of the surgical instrument. In a telesurgical system, a surgeon may be provided with an image of the surgical site at a surgical workstation. The surgeon operates the surgical procedure on the patient by manipulating a master control device that in turn controls the movement of the instrument operated by the servomechanism while viewing a 2D or 3D image of the surgical site on the display. To implement.

  Servo mechanisms used for telesurgery often accept input from two master controllers (one for each of the surgeon's hands) and include two or more robotic arms or manipulators, each with a surgical instrument attached. May be included. Operational communication between the master controller and the associated robot arm and instrument assembly is typically achieved via a control system. The control system typically relays at least one input command from the master controller to the associated robot arm and instrument assembly and back from the instrument and arm assembly to the associated master controller, eg, in force feedback or similar cases. Including processor. An example of a robotic surgical system is Intuitive Surgical Inc. of Mountain View, California. DA VINCI® system available from

  The roles and interactions of the people who make up the telesurgical team can differ from conventional surgery. Since telesurgery is often performed at an internal surgical site, at least some of the persons working under the direction of the leading surgeon (or other robotic system operator) have direct access to the ongoing tissue manipulation or the Can not have a direct visualization of the operation. For example, when the surgeon may wish to use different surgical instruments during different stages of the surgical procedure, the surgical assistant in the operating room removes the first surgical instrument (such as an electrosurgical scalpel) from the manipulator and the different surgical instruments It can be replaced with a needle holder or the like. Similarly, the assistant can reposition the surgical instrument during the procedure so that the instrument can perform internal surgery from a second different access site rather than proceeding to the procedure from the first minimally invasive access site. Progress to site. More complex robotic systems (and team interactions) can also be used. For example, because surgery is often performed using more than two tools, an input device is provided to one or more additional surgeons, each of which adds at least one surgical instrument by a robot ( For example) control.

  Although new telesurgical systems, devices and methods have been found to be very effective and advantageous, still further improvements are desirable. In general, it may be desirable to provide improved robotic and / or surgical devices, systems and methods, particularly for performing telesurgical procedures. Also improved to interface with telesurgical devices to communicate between members of the telesurgical team and provide improved efficiency in making better use of telesurgical capabilities and improving patient outcomes It may also be desirable to provide technology. It may be particularly beneficial to avoid unnecessary interruptions and distractions of the surgeon or other system operator and to avoid delays and / or mistakes in the coordinated activities of the telesurgical team.

(Summary of Invention)
The present invention relates generally to medical and / or robotic devices, systems and methods. The exemplary embodiments of the present invention provide visual indicators associated with each manipulator assembly (and thus each surgical instrument) of a multi-arm telesurgical system. Exemplary indicators include multi-color light emitting diodes (LEDs) that allow the indicator to display any of a wide variety of signals by combinations of colors, flashing, and the like. By establishing and using a lexicographic method for the appropriate indicator signal, the indicator can, for example,
Whether the manipulator and the surgical instrument are following the leading surgeon's input movement command,
Whether the movement of the surgical instrument is restricted (eg when the manipulator is in clutch mode and manual movement is possible);
Whether the surgical instrument is at, near or beyond its intended service life,
Whether the second surgeon has control of the surgical instrument,
-The obstacle prevents the robot of the surgical instrument from moving;
And / or similarities may be identified.

  The surgeon may also optionally initiate a signal from one or more of the indicators to identify the associated surgical instrument to be removed and replaced. Surgeons often remain immersed in ongoing surgical procedures, for example, because it can be difficult to determine which instruments were previously controlled by the surgeon's right hand and should be replaced at this stage, Such indicators can greatly facilitate communication between telesurgical systems and / or members of a telesurgical team, which can increase efficiency and improve patient outcomes. An identifiable signal is output from the selected indicator to a nearby person.

  In a first aspect, the present invention provides a robotic method that includes moving a first end effector of a first manipulator assembly in response to a first robot command. The first manipulator assembly has a first indicator. The second end effector of the second manipulator assembly is moved in response to the second robot command. The second manipulator assembly has a second indicator. A command is sent from the processor and the command is selectably directed to the first indicator and / or the second indicator.

  In many embodiments, the end effector includes a working end of a surgical instrument. The person receiving the identifiable signal is often a member of a robotic surgical team in the operating room and the processor acts as a master / slave telesurgical controller. In such an embodiment, the move command can be entered by a system operator, and the system operator can also select which of the manipulator assemblies should output the first signal. This allows the system operator to continue to concentrate on moving the end effector shown on the display, for example while communicating with the assistant regarding a particular surgical instrument. For example, rather than telling the assistant, “Replace the electrosurgical scalpel of the arm that is now moving back and forth with a needle driver,” the surgeon simply asks for a needle driver instead, and the appropriate manipulator assembly Can be activated. Optionally, the processor may select an appropriate indicator and manipulator assembly, such as when a tool attached to the manipulator reaches or exceeds its intended service life.

  The indicator often includes a visual indicator and the first signal includes a visual pattern such as blinking or the like, an identifiable color, or other identifiable visual signal. In the exemplary surgical system, each of the indicators includes a plurality of light emitting diodes (LEDs). A variety of alternative indicators may be used including any of a variety of light sources capable of generating audible indicators that generate signals of various colors, tones or languages. Preferably, a plurality of separately identifiable signals may be output from each indicator, thereby providing the user interface with communication to an assistant or similar person regarding the associated manipulator assembly.

  Typically, each manipulator assembly includes a manipulator that movably supports the tool holder and a tool releasably attached to the tool holder. A tool typically includes an end effector. The first identifiable signal may be, for example, the state of the tool, which particular manipulator assembly is associated with operating on a particular input device, the overall status or state of all manipulator assemblies, the selected manipulator An identification of one or more components of the assembly or the like may be indicated. Some lists or lexicographical methods that explain the meaning of each identifiable signal are often provided or known by the person receiving the signal, who is often the manipulator assembly from which the signal is output. Take action in response to the signal, such as reconfiguring. Reconfiguration replaces the tool of the manipulator assembly with another tool having a different (or the same) end effector, changes the mode of the manipulator assembly to activate or inhibit the end effector master / slave movement, or the like Can be included.

  It is often beneficial to include easily distinguishable signal types or groups. For example, if the first signal includes yellow, the yellow may communicate a warning that the associated manipulator assembly remains functional but needs attention now or in the future. A signal containing red may communicate a fault sufficient to interrupt movement of the end effector along the robot system chain.

  Various improvements may be implemented by using a manipulator assembly indicator. For example, a system operator entering a move command benefits from a graphical indicia on the operator's display that corresponds to the first identifiable signal. Thus, when indicating by flashing the indicator that the tool is nearing the end of its life, etc., the same information is displayed on the instrument as shown on the display by simple flushing of the icon on the operator's display screen. It can be communicated to the system operator by superimposing the flash color of the end effector, or the like. In some embodiments, in addition to indicating which currently installed tool or end effector should be replaced, the processor may also flash the LED at the appropriate location on the tool tray. , Or the like, may apply a voltage to another indicator associated with the new tool that is currently desired.

  In another aspect, the present invention provides a surgical robot method including inputting a robot movement command from a system operator to an input device. The surgical end effector of the manipulator assembly moves in response to robot commands. The system operator sees the end effector movement on the display as he enters the command. An identifiable visual signal is transmitted from a manipulator assembly visual indicator to a nearby person. In response, the person manually reconfigures the manipulator assembly.

In yet another aspect, the present invention provides a surgical robotic system comprising a first manipulator assembly having a first indicator and a first end effector. The first end effector is movable in response to the first movement command. The second manipulator assembly has a second indicator and a second end effector. The second end effector is movable in response to the second movement command. The processor is coupled to the first and second indicators for selectively outputting a first signal that can be identified by a person close to at least one of the indicators.

(Detailed description of the invention)
The present invention generally provides improved robotic and / or medical devices, systems and methods. Embodiments of the present invention are particularly well suited for telesurgery, and the addition of a user interface that can enhance communication between a surgical system operator, an assistant, any other member of a telesurgery team, and / or a telesurgery system Often provides a form of Other embodiments of the present invention are particularly well suited for use in other remote or robotic environments using robotic systems having multiple manipulators.

  1-3 illustrate the components of a robotic surgical system 1 for performing minimally invasive robotic surgery. System 1 is similar to the system described in more detail in US Pat. No. 6,246,200, the entire disclosure of which is hereby incorporated by reference. A system operator O (typically a surgeon) performs a minimally invasive surgical procedure on a patient P lying on the operating table T. The system operator O operates one or more input devices or masters 2 at the surgeon's console 3. In response to the surgeon's input command, the computer processor 4 of the console 3 directs the movement of the endoscopic surgical instrument or tool 5 via the patient-side robot manipulator system 6 (in this example a cart loading system). The operation of the servo mechanism is brought about.

  Typically, the manipulator system 6 includes at least three robot manipulator assemblies. Two linkages 7 (attached to both sides of the cart in this example) are manipulators using linkages 7 that generally support the base of the manipulator 8 in a fixed location during at least part of the surgical procedure. 8 is supported and positioned. The manipulator 8 moves the surgical tool 5 for robotic manipulation of the tissue. One additional linkage 9 (in this example attached to the center of the cart) controls the movement of the endoscope / camera probe 11 to capture an image (preferably stereoscopic) of the internal surgical site. The manipulator 10 is supported and positioned. The fixable parts of the positioning linkages 7, 9 of the patient side system are sometimes referred to herein as "setup arms".

  An image of the internal surgical site is shown to the operator O by the stereoscopic display 12 of the surgeon's console 3. The internal surgical site is simultaneously shown to assistant A by assistance display 14. Assistant A may assist before or during the surgical procedure. Prior to surgery, Assistant A typically covers at least a portion of the system with a sterile drape. Such draping of the system includes attaching a sterile adapter, cannula, and / or the like to the manipulator 8, switching to one or more manipulators in a clutch mode that can be manually engaged, and so on. Can include switching. The assistant A also pre-positions the manipulator assemblies 8 and 10 with respect to the patient P using the setup linkage arms 7, 9, the tool 5 from one or more surgical manipulators to an alternative surgical tool or instrument 5 ′. Assists in exchanging, operating medical instruments and devices without the associated robot, and manually moving the manipulator assembly so that the associated tool can access the internal surgical site, such as through different apertures. Some or all of these activities may be facilitated by providing feedback to Assistant A via the indicators described herein, where the indicators are in the state of the manipulator assembly, a tool attached to the manipulator assembly Often provides feedback to the assistant regarding the status of the patient and / or the status of the robotic surgical system.

  In general conditions, the linkages 7, 9 are primarily used during the setup of the patient-side system 6, and typically remain in a fixed configuration during at least a portion of the surgical procedure. Each of the manipulators 8, 10 is provided with a driven linkage that is operatively linked under the direction of the surgeon's console 3. One or more joints of the setup arm may be optionally driven and controlled by a robot, but at least a portion of the setup arm may be configured for manual positioning by assistant A. Each associated combination of a setup fitting, manipulator and tool is encompassed within the term “manipulator assembly” as used herein. However, some manipulator assemblies may not include setup fittings, and manipulator assemblies do not always include tools.

  For convenience, a manipulator such as manipulator 8 that supports a surgical tool used to manipulate tissue is sometimes referred to as a patient-side manipulator (PSM). On the other hand, the manipulator 10 that controls an image capture device or data collection device such as the endoscope 11 may be referred to as an endoscope-camera manipulator (ECM). The manipulator may optionally operate, operate and control a wide variety of instruments, tools, image capture devices and the like useful for surgery.

  As can be seen in FIGS. 1 and 2, an indicator 20 is disposed on each manipulator assembly. In the exemplary embodiment, the indicator 20 is placed on the manipulators 8, 10 near the interface between the manipulator and its attached tool 5. In an alternative embodiment, the indicator 20 can instead be placed on the setup joint 7, 9, tool 5, other place on the manipulator 8, 10, or the like, and the signal generated by a particular indicator However, the indicator is preferably close enough to the tool so that when viewed by assistant A, the signal can be easily related to a particular tool. In FIG. 1, additional indicators 20 are shown in the rack or other structure that supports additional tools 5 ', with each indicator again associated with a particular tool (or type of tool).

  As can be seen in FIG. 1, the system operator O is mainly devoted to the environment of the workstation 3 and the interaction with the workstation 3. The system operator views the image provided by the display 12 and manipulates the input device 2, and in the exemplary embodiment, the processor 4 causes the end effector image to follow the movement of the input device by the hand of the system operator O. To the movement of the end effector of the tool 5.

  It may be advantageous to avoid diverting the attention of the system operator O during surgery that would require the system operator O to shift attention from the internal surgical site. Even when Assistant A replaces tool 5 with a replacement tool 5 ', the system operator can continue to manipulate the tissue with another tool or view the surgical site to monitor bleeding and / or the like. You can hope to continue. Nevertheless, it can be difficult for the system operator to communicate clearly with assistant A regarding which tool 5 is to be replaced by an alternative tool. In particular, tools related to the right hand of the system operator O are often not placed to the right of the endoscope, especially as seen by an assistant, so that the endoscope 11 can be in any convenient orientation.

  In order to clearly identify the tool 5 exchanged by the assistant A, the system operator O generates a visually identifiable signal that the indicator 20 on the manipulator assembly associated with the particular tool 5 can be viewed by the assistant. Commands can be entered into the workstation 3 (eg, by pressing a button on the input device 2, activating a foot pedal, entering a voice command, or the like) ). Corresponding graphical display of signals, presentation of appropriate icons, superimposing text on the surgical site, using image processing that superimposes false color on the appropriate end effector image, or the like Can be provided to the system operator O on the display 12. In response to the signal on indicator 20, assistant A may remove and replace the identified tool 5. Optionally, each alternative tool 5 ′ may also have an associated indicator 20 that allows the processor to send a signal to indicate which alternative tool should be attached to the robot system for the system operator O. to enable.

  There are a number of additional uses of the indicator 20 in the telesurgical system 1. For example, when assistant A prepares a surgical procedure, when reconfiguring the manipulator system 6 for different stages of the surgical procedure, when replacing a tool with a replacement tool 5 ', etc. The positions of the tool 5 and the endoscope 11 are determined manually. During such manual reconfiguration of the manipulator assembly by Assistant A, the manipulator assembly may be put into a mode different from that used during master / slave telesurgery, and the manually repositionable mode is sometimes clutched ( (Clutch) mode. The manipulator assembly may change the tissue manipulation mode and the clutch mode in response to an input such as pressing a button on manipulator 8 (or other component to the manipulator assembly), and assistant A changes the manipulator mode. to enable. By generating an appropriate visually identifiable signal using indicator 20 whenever the manipulator is in clutch mode, Assistant A can avoid errors and improve the efficiency of the surgical procedure.

  For example, when no tool is attached to the manipulator, and when a sterile adapter or interface is not properly attached between the tool 5 and the manipulator 8, the instrument attached to the manipulator is not compatible with that manipulator. If the instrument has reached its service life limit and / or similar, the indicator 20 may also indicate an associated identifiable signal. For some of these signals, the system operator O may initiate signal generation and may specify the associated manipulator assembly in which the signal is to be generated. In other cases, the processor 4 may initiate a signal and / or indicate which manipulator assembly should be indicated. For example, in the case of a power failure, the robot system 1 can continue to operate using a backup battery. In order to instruct Assistant A that a power failure has occurred, the indicator 20 in all manipulators may flash, optionally with a yellow light as a warning. When the battery power is depleted and the robot system 1 can no longer continue to provide robotic movement of the tool, all indicators 20 will flash red, thereby indicating a system failure. A wide variety of alternative signals may also be provided, some of which are indicated by the exemplary lexicographic method of FIGS.

FIG. 4 illustrates a perspective view of the connected surgical tool or instrument 5. Tool 5 has a proximal housing 24 that interfaces with a manipulator tool holder, which typically provides quick release mounting engagement via a sterile adapter or interface. To do. Tool 5 includes an elongate shaft 23 that supports an end effector 28 relative to a proximal housing 24. The proximal housing 24 includes a drive mechanism that receives and transmits a drive signal or drive action between the manipulator 8 and the end effector 28. Proximal housing 24 also generates a signal for transmission to processor 4 to identify the type of tool, indicate the remaining service life of the tool, and / or the like. Including the resulting network. An exemplary network may include a memory, such as a Dallas ^™ part, and a method for transmitting information between the memory of the tool 5 and the processor 4 is described in the application entitled “Tool Memory-Based on May 4, 2004. Software Upgrades for Robotic Surgical Application No. 10 / 839,727, the entire disclosure of which is hereby incorporated by reference. The coupled wrist 29 may provide two degrees of freedom of motion between the end effector 28 and the shaft 23 so that the shaft provides the end effector 28 with three degrees of freedom in the patient's body. In addition, it may be rotatable relative to the proximal housing 24 about the axis of the shaft. Control over actuation of the end effector 28, such as opening and closing of a jaw or the like, may represent additional degrees of freedom for a total of four degrees of freedom at the distal end. In some embodiments, the indicator 20 can be attached to the housing 24.

  Referring now to FIG. 4, a perspective view from above of an alternative modular manipulator support assembly 30 that can be attached to the operating room ceiling is provided. Modular manipulator support 30 aligns and supports the robot manipulator system with respect to the set of desired surgical incision sites on the patient's body. The modular manipulator support 30 generally includes an alignment platform 36 and a plurality of configurable setup linkage arms 38, 40, 42, 44 that can be coupled to the alignment platform. Each arm movably supports an associated manipulator 32, 34, and the associated manipulator 32, 34 likewise movably supports an associated tool or image capture device. Orientation platform 36 also supports assistant display 104, which may be used for setup, instrument changes, viewing procedures, and the like. The structure and use of any component of the modular manipulator support assembly 30 is similar to that described above with respect to the manipulator system 6 and is the same as the name of “Modulator Manipulator Support For Robotic Surgical” filed on January 24, 2005. More fully described in pending US patent application Ser. No. 11 / 043,688 (Attorney Docket No. 017516-009900 US), the entire disclosure of which application is incorporated herein by reference. In general, as described above, each manipulator 32, 34 of the modulator manipulator support 30 may include an indicator 20.

  The manipulator 32 is shown in more detail in FIG. 5 which also shows the indicator 20 near the tool holder 52. An exemplary indicator 20 is shown in more detail in FIG. 6 and alone in FIG. 7 (some of the internal components are shown schematically in dotted lines). The exemplary indicator 20 generally comprises a transparent and / or translucent polymer body 54 to which a pair of light emitting diode (LED) arrays 56 are attached. The LED 56 includes a red LED, a blue LED, and a green LED. Exemplary LEDs are commercially available from ____ in ____, while exemplary polymer bodies may include materials such as ____. (Please specify the name and location of your LED supplier and the material of your tower cap, if appropriate). Each array of LEDs can be independently energized to any of a plurality of illumination and brightness levels, such that the indicator 20 generates signals in a variety of colors, as schematically illustrated in FIG. Enable. Furthermore, the overall level of illuminance from the indicator 20 can be varied, blinking and lighting on and off, alternating two different colors, alternating two different illuminance levels, two different colors simultaneously By displaying or doing something similar, the pattern can be added to the cover signal. The rate of flashing can also be controlled or changed in more complex modulation patterns (long and short flashing, Morse code, etc.).

  Since different colors can be combined with different illumination levels and different modulation patterns in the signal, a very large number of independently identifiable signals can be generated, the number of which is often more than three separately An identifiable signal, typically more than 10 separately identifiable signals, and optionally more than 100 separately identifiable signals. Interpretation of identifiable signals can be facilitated by a list that associates signals with their meanings, such as those included in FIG. In some embodiments, a relatively simple signaling scheme with a more limited number of signals output by indicator 20 is combined with supplemental text or graphics output from assistant display 114 or the like. Can be done. Accordingly, the assistant may know that it should look for additional information on the assistant display in response to one or more signals.

  Any of a variety of signal conventions may be established and / or used to facilitate interpretation of the signal generated by the indicator 20. For example, as can be understood with reference to FIG. 11, a signal that includes a yellow color may generally indicate a warning. Optionally, the manipulator assembly may continue to function while its indicator 20 displays such a yellow warning signal, but the assistant may understand that certain actions may be recommended. The specific action or meaning of the warning signal may depend on other aspects of the signal, such as other colors plugged into the flashing yellow lighting pattern, the speed of flashing or the like. A signal that includes red may indicate a current or imminent fault that may or may soon prevent operation of the manipulator assembly. Green can optionally indicate that normal operation is in progress, blue can indicate that an instrument or tool is engaged, and / or that a guided tool change is in progress or required You can direct. Purple may indicate that the second surgeon or system operator is actively controlling the manipulator assembly or doing something similar. A slowly blinking light may generally indicate a less urgent state than a fast blinking indicator 20. Some of these possible conventions are illustrated graphically in FIG.

  Referring now to FIG. 8, a schematic block diagram of a somewhat more complex system 60 is provided. An exemplary collaborative telesurgical system that can be modified to take advantage of the additional user interface provided by the indicator 20 is described in more detail in US Pat. No. 6,659,939, which is incorporated by reference herein in its entirety. The disclosure is incorporated herein by reference. In the exemplary system of FIG. 8, the first system operator O 1 provides input to the first input device 2. The processor 4 selectively couples the move command from the first input device 2 to any of a plurality of manipulator assemblies such as, for example, manipulator A and manipulator D. The second system operator O2 inputs a movement command to the second input device 2 to achieve movement of the manipulator assembly B of the manipulator 32.

  If the second system operator O2 wishes to replace the tool 5 attached to the manipulator assembly B with an alternative tool 5 ', eg, tool F, the system operator will assist the assistant A to install the tool F on the manipulator assembly of assistant A. A can be instructed verbally. The indicator 20 of the manipulator assembly B generates a signal in response to the appropriate input by the second system operator O2 to clearly indicate to the assistant A which tool the manipulator assembly is to be replaced.

  As pointed out above, additional indicators can optionally be associated with each of the alternative tools 5 ', which need of verbal instructions to the assistant regarding which alternative tool should be attached to the manipulator Also precedes. To that end, an alternative tool 5 'can often be included in a tool rack 62 coupled to the processor 4 to provide communication between the alternative tool 5' circuitry and the processor. This may allow the processor to read identification information from the tool, thereby allowing the processor to determine which alternative tool or tool type is available and / or suitable for attachment to the manipulator system. It becomes possible to decide. An LED or other indicator may be associated with each alternative tool 5 'included in the tool rack, and the processor 4 may be in the tool rack to activate one or more indicators associated with one or more tools. A signal may be transmitted. Thus, if the system operator O1 indicates to the processor 4 that he wishes to replace the attached tool 5 (eg, tool B of manipulator B) with a different type of tool, a list of available tools and / or tool types Can be displayed to the system operator. In response to the selection of the system operator (e.g., the tool type corresponding to tool F), tool B and indicator 20 associated with tool F may be activated and assistant A that these two tools should be replaced. To instruct.

  The processor 4 typically includes data processing hardware and software, which typically includes machine readable code. The machine readable code implements software programming instructions to implement some or all of the methods described herein. Although the processor 4 is shown as a single block in the simplified schematic diagram of FIG. 8, the processor may include a number of data processing circuits, at least a portion of which is optionally performed near the input device 1. Some of them are executed in the vicinity of the manipulator B. Any of a wide variety of centralized or distributed data processing architectures may be used. Similarly, the programming code can be implemented as a number of separate programs or subroutines, or can be integrated into a number of other aspects of the robotic system described herein.

  Referring now to FIG. 9, flowchart 70 schematically illustrates a method for implementing an embodiment of the present invention. Method 70 begins with a state change of a manipulator, tool, system, or the like. For example, the assistant may actuate the manipulator's clutch mode button, the tool may be achieved at the end of its service life, a manipulator failure may be detected, or otherwise. In other embodiments, the system operator initiates method 70 by requesting a new tool 74, or in some other way, which one or more manipulator assemblies are perceived by the assistant or some other person. Can be indicated.

  Regardless of whether the signal changes or is initiated by a system operator, the processor typically sends an appropriate command to one or more manipulator assemblies 76, and in response, the indicator for that manipulator assembly is A visual signal 78 is displayed. Optionally, it can be shown on the corresponding graphic system operator display 80, thereby allowing the system operator to continue to concentrate on the internal surgical site.

  In response to the visual signal, another person, such as an assistant, may optionally reconfigure the manipulator assembly 82. For example, the assistant can remove and replace the tool (with its end effector) or manually reposition the manipulator linkage to move the end effector to the desired position. In some embodiments, the assistant may simply monitor the manipulator assembly in response to one or more visual signals and if the visual signal changes to indicate that such measures are appropriate, Optionally prepare to take appropriate action.

  10-14 illustrate the meaning of the various signals that can be generated by the exemplary multi-color LED indicator described herein. FIG. 10 illustrates a possible dictionary editing method for using an indicator as a manipulator user interface (“UI”), while FIG. 11 illustrates some common meanings of signal colors from the indicator. FIG. 12 shows an alternative general meaning of the two three-color LED indicators 20 included in each manipulator assembly. By transmitting these or other color signals with sufficient brightness through a transparent or translucent plastic cap at the position of the manipulator assembly along the tool insertion axis away from the patient, the signal is It can be easily identifiable over a large area. The red, green and blue elements of each LED array have brightness that can be controlled independently, and the two LED arrays of indicators can be controlled independently, so that a wide variety of distinguishable signal colors are generated. obtain.

  FIG. 13 specifically identifies the state of the system, manipulator assembly and / or tool that may be associated with a number of specific signals from the manipulator assembly indicator. As can be understood with reference to FIGS. 6 and 7, simultaneous flashing includes flashing of both LED arrays within a single indicator of the manipulator assembly. Alternating flashing involves activating two LED arrays with out-of-phase flashing so that when one LED array is on, the other is off. Still further additional signals can be generated by the indicator to communicate alternative information. For example, a signal (such as a fast blinking green) is valid and accepted by a component (cannula, sterile adapter, tool or surgical instrument, or the like) that is recently or just installed in the manipulator system You can show that. An alternative signal may indicate that a tool change is required by the system operator, an activatable instrument (an electrosurgical instrument or the like) is activated by the system operator, and so on. Various signal characteristics may optionally be associated with recoverable and non-recoverable failures. Accordingly, a wide variety of yet further alternative signals may be included.

  Although described in some detail for purposes of clarity of understanding and by way of example, various changes, modifications, and modifications will be apparent to those skilled in the art. Accordingly, the scope of the invention is limited only by the appended claims.
